IMPROVED'MACHINE, FOP-. 'MANUFACTURE OF METALLIC ,(IAR'I`RIDGES.v

Specification forming part of Letters Patent N0. 3l,695dated March 19,lEGl.

.To all whom it may concern:

Be it known that I, ETHAN ALLEN, of foreester, in the county ofVorcester, in the State of Massachusetts, have invented a new andImproved Machine for the Manufacture of Metallic Cartridges; and I dohereby declare that the following is a full and exact description of thesamefreference' being had to the accompanying drawings, and to theletters marked thereon, which make a part of this specification, inwhich- Figure 1 is a vertical longitudinal section through the center ofthe machine, and Fig. 2 is a top View or elevation, and Fig. 3 is a faceView, of the plate that holds the rollers and cutters; and Fig. 4 is anend view of the head or clamp which holds the cartridge while beingoperated upon.

The nature of my invention consists in so arranging a set of rollers,cutters, and a holder for cartridges operating automatically that thecopper may be rolled into the bullet sufficiently to hold it secure, andcrease the ball for the reception of a lubricating material.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A is a baseplate.

B is a heacle'tock.

C is a ttihstcek.

D is ahollow shaft,in which is coiled a spiral spring, a, and works insuitable bearings, b b.

E is a spindle, which is intended to slide back and forth within theshaft D, and is secured to it by means ofthe screw o, which works inslot p of shaft E. One end o f shaft or spindle E is enlarged, and has aface-plate, F, in. which slide in suitable grooves two pieces, f f,which hold each a corrugatedI roll, h h, and two similar pieces, g g,which slide in grooves and hold the knives 751s. There are four levers,'i i i i, (one of which is not seen in the drawings,) which are hung inspindle E at Z l Z Z, and connected at one end with pieces f f and g g,while the other is beveled in order to slide on the inclined surface m mof shaft D.

' G is a short spindle within spindle E, which operates as a dead-centerwhen the cartridge is pressed against it to be operated upon.

H is a' shaft, which slides back and forth in suitable bearings, qq,'within which there is a small spindle, L, which is intended to slideback and forth within shaft H, and is kept in position by the spiralspringr, one end of which bears against the inside shoulder of the outershaft, H, and the other against the collar s of spindle L. On one end ofshaft H thereis an oblong head, M, in which slides in grooves a jaw orclamp, N. v There is also a lever, P, which is hung to the head M at t,and to the sliding jaw N at n a.

R is a wheel, which is hung in the rear en d of lever P by a pivot orshank, n, which slides up and downthrough the end of lever P, and isregulated by spring o, which rests upon the top of shank u, and isconnected to lever P by means of screw 2. The jaw `N is closed by meansof wheel It rising on the inclined plane 4, and kept rmly closed byrunning on the level plane 5 when the head M is moved forward for thatpurpose. There is attached to the rear end of shaft H an oblong block,T, with a regulating-serew, 6, in its upperpart, while at its lower orunder side is attached a long lever, XV, which is attached to thebase-plate A by means of arm y, connected to a standard at 7.

Z is 'an arm or bracket, firmly secured to tail-stock C by means ofscrew 8, and its use is to slide spindle L forward through shaft 'H whensaidshaft H is moved far enough back to have the head of screw 9 strikethe projection 10 on arm Z, and thereby throw the car tridge outof thejaws after it has been operated upon.

The operation is as follows Powervis appliedto shaft D, and through thatto spindle E, which gives spindle El and face-plate F a rotary motion.The operator now stands with his right hand on the handle'of lever W andputs the cartridge into the jaws at 12 with his left. The lever Wisnowfdrawn toward the center of the machine, which. closes the jaws andholds the cartridge` firmly, by means of the inclined plane 4 andleverP. Y Shaft "H is .now moved forward and the bullet end of the cartridgeis received into the end of center G. The head F and spindle E, beingforced back toward the head-block B, closes the rolls h h and knives k kin-upon the cartridge by means of levers z' i t and inclines an. m m mf,whichl rolls h h, being corrugated, close .the metal in'to the ball and'form the required creases, while the knives k k are so adjusted as topare o' the metal which is raised by the rolling process. The lever XVis now carried backward until the rear end of spindleL comes in contactwith the projection 10 on arm Z, which carries said spindle L throughthe jaws at 12 and throws the' finished cartridge out. The spindle L iscarried back to its place by means of spring r as soon as it is releasedfrom the pressure at the end against projection 10, and the operation isrepeated as before.

What I claim as my invention, and desire to 4secure by Letters Patent,is-

The combination of rollers h h, knives 7a k, levers z' inelines m m m m,With jaw N, inclined plane 4, spindle L, and arm Z, substantially asspecified, and for the purpose set forth.
